Definitions

  • Chucks which removably secure articles, such as tools or work-pieces, to machine tools, are well known in the art.
  • Such chucks may employ flexible collets, which may expand or contract radially, to releasably grip the article in the chuck.
  • the gripped article may slide axially relative to the chuck, especially when relatively large axial cutting forces act on the article. Such axial sliding is undesirable, and may adversely affect the quality of the work-piece, the life of the tool, or both.
  • EP-A1-0 263 982 discloses a cutting tool assembly having a chuck and a collet for chucking a cutting tool.
  • the collet has a through-bore in which a shank of the cutting tool can be releasably secured.
  • the collet is transferable between a releasing position in which the tool shank is accommodated in, and slidable through, the collet bore; and a securing position in which the tool shank is secured in the collet bore buy a gripping force of the collet.
  • a cutting tool assembly having a longitudinal axis L defining a front-to-rear direction.
  • the assembly comprises a collet and a shank.
  • the collet has a through-bore extending along said longitudinal axis, an inner surface of the collet comprising a peripheral inner slot and a crest, the crest comprising a collet front, an axially rearwardly facing first slot face, and a front inner surface extending between the collet front and the first slot face, at least a portion of the front inner surface being radially inward of the peripheral inner slot.
  • the shank extends along the longitudinal axis and is releasably secured in said through-bore, the shank comprising a shank peripheral envelope having a peripheral shank slot formed therein, the shank slot defining a trough comprising an axially rearwardly facing first slot side, an opposing axially forwardly facing second slot side, and a slot base extending therebetween.
  • the collet is transferable between a releasing position in which the shank is accommodated in, and slidable through, the collet through-bore, with the crest positioned outside of the trough; and a securing position in which the crest is at least partially accommodated in the trough.
  • the cutting tool assembly comprises: a chuck with a receiver, which has a bore, and a nut; the collet that is accommodated in the bore of the receiver, whereas the nut is threadingly engaged to the receiver and abuts the collet.
  • the nut comprises a nut forcing cone which abuts the collet.
  • the shank peripheral envelope has a plurality of peripheral shank slots formed therein.
  • the plurality of peripheral shank slots are evenly spaced apart along an axial portion of the shank.
  • Fig. 1 is a perspective view of an assembly comprising a chuck and an article secured therein in accordance with an exemplar embodiment

  • the flange rear face 54 extends inwardly away from the flange peripheral envelope 52 to a mount front 56 of a rear mount 58.
  • the mount 58 has a mount envelope 60 which extends rearwardly from the mount front 56 coaxially with the longitudinal axis L while tapering inwardly to a mount rear 62.
  • the mount 58 is of a generally frustoconical shape, and is adapted to be releasably mountable in a rotary machine tool, such as, for example, a milling machine (not shown).
  • a rotary machine tool such as, for example, a milling machine (not shown).

  • the front inner surface 96 extends across the plurality of front fingers 81 and axially rearwardly from the collet front 74 to an axially rearwardly facing first slot face 100.
  • the first slot face 100 extends radially outwardly from the front inner surface 96 to a radially inwardly facing slot floor 102.
  • the slot floor 102 extends axially rearwardly from the first slot face 100 to an axially forwardly facing second slot face 104.
  • the second slot face 104 extends radially inwardly from the slot floor 102 to the rear inner surface 98.
  • the first slot face 100, the front inner surface 96, the collet front 74, and two adjacent first slots 78 define an inner collet crest 106 on each of the first fingers 81.
  • the nut 38 has a nut outer envelope 108 extending rearwardly from an axially forwardly facing nut front 110 to an axially rearwardly facing nut rear 112.
  • a nut inner envelope 114 extends forwardly from the nut rear 112 to the nut front 110.
  • the nut inner envelope 114 has a female thread 116 formed therein, extending forwardly from the nut rear 112, to terminate adjacent a nut forcing cone 118.
  • the nut forcing cone 118 extends forwardly from the female thread 116 to the nut front 110 while tapering inwardly, to form a generally frustoconical shape defining an acute nut cone angle ⁇ with the longitudinal axis L.
  • the nut cone angle ⁇ is equal to the front cone angle ⁇ F .
  • the shank 32 has a shank peripheral envelope 120, which extends peripherally thereabout, generally parallel to the longitudinal axis L.

  • the first slot side 124, the slot base 126, and the second slot side 128 define a shank trough 130.
  • the chuck 30 is assembled by placing the collet 36 with the collet rear 76 adjacent the bore rear end 66, with the rear outer surface 86 of the collet 36 abutting the bore surface 65, and with the outer slot 82 and the front outer surface 84 of the collet 36 extending forwardly relative to the receiver front 46.
  • the nut 38 is placed on the receiver 40 with the female thread 116 of the nut 38 engaging the male thread 44 of the receiver 40, and is threadingly tightened thereon, until the nut forcing cone 118 abuts the front outer surface 84 of the collet 36, so that the chuck 30 is brought to a releasing position.
  • the crest 106 is located outside of the trough 130 so that the shank 32 may be inserted and slid relative to the through-hole 68.
  • the shank 32 is inserted into the through-hole 68 of the collet 36, so that the shank peripheral envelope 120 faces the through-hole envelope 70, and .the trough 130 of the shank 32 is set opposite the crest 106 of the collet 36.
  • the article is clamped in the chuck 30 by bringing the chuck 30 to a clamping position, by further tightening of the nut 38 relative to the releasing position.
  • the collet 36 contracts in a radially inward direction, until the rear inner surface 98 of the through-hole 68 abuts the shank peripheral envelope 120, bringing the chuck 30 to the clamping position, whereby the shank 32 is clamped in the chuck 30.
  • the chuck 30 is brought to a securing position, by continuing to tighten the nut 38 to the receiver 40.
  • the collet 36 can not be further urged rearwardly in the bore 64 and therefore bends, so that the crests 106 of each of the first fingers 81 are urged into the trough 130 of the shank 32 until the front inner surface 96 abuts the slot base 126.
  • the shank peripheral envelope is cylindrical, it may take on different shapes, such as oval or polygonal, so long as the inner surface of the collet is correspondingly formed.
  • an article should not be construed as limited to a shank of a cutting tool; the angles ⁇ , ⁇ , ⁇ F and ⁇ R may be modified to suit other geometrical configurations; the collet does not necessarily have a converging frustoconical rear portion; urging the crests of the collet into the trough of the article is not necessarily accomplished by tightening of a nut or by a conical portion formed thereon; and, a trough may be formed on the collet, while a crest may be formed on the article.
  • the crest must not be construed as necessarily being an integral part of the article or the collet. Therefore, unless otherwise such changes and modifications depart from the scope of the present invention, they should be construed as included therein.
